SQA and SQC in CMMI Verification (VER)

The purpose of Verification is to ensure that selected work products meet their specified requirements Theses activities are only carried out by SQC, the role of SQA would be to make sure that SQC had documented procedures, plans etc. by audit. SQA would also measure the effectiveness of the Verification processes by tracking defects that were missed by SQC during Verification. Note the term Verification, as opposed to Validation. In essence Verification answers the question ‘Are we building the product correctly’ while Validation answers the question ‘Are we building the correct product’. Validation demonstrates that the product satisfies its intended purpose when place in the correct environment while Verification refers to building to specification. The FURPS+ model identifies both Customer and Product requirements; Verification applies to both these types of requirements and can be applied to the intermediary work products. Design or Code reviews are examples of Verification. These terms Verification and Validation are often mixed, CMMI makes this comment about the distinction:- Although “verification” and “validation” at first seem quite similar in CMMI models, on closer inspection you can see that each addresses different issues. Verification confirms that work products properly reflect the requirements specified for them. In other words, verification ensures that “you built it right.” While SQC carries out all the Verification activities the Verification process itself is still subject to SQA and process improvement.
